4.5" 2023-2026 Ford F250 / F350 Super Duty 4WD (w/diesel engine) Lift Kit (w/Radius Arms) by Rough Country

400330 Rough Country 4.5-inch lift kit is designed for Ford F-250 and F-350 Super Duty trucks, delivering improved ground clearance, aggressive styling, and enhanced off-road capability while maintaining stable on-road handling. Engineered to eliminate factory rake and level the truck from front to rear, this system provides the clearance needed for up to 35-inch tires and a more commanding stance.

Built for durability and suspension performance, this kit features heavy-duty tubular radius arms with a large 2-inch outer diameter design for increased strength and improved suspension geometry. These radius arms bolt directly into the factory mounting locations without requiring drop brackets, helping simplify installation while maintaining proper alignment and suspension operation. Lifted front coil springs, sway bar drop brackets, and a track bar relocation bracket work together to preserve factory-like steering feel and predictable handling characteristics. In the rear, heavy-duty fabricated lift blocks provide superior durability compared to traditional cast blocks while helping maintain proper ride quality. Anti-axle wrap block design reduces unwanted axle movement under acceleration and towing loads, improving overall stability and suspension control.

This Rough Country 4.5-inch lift kit is available with multiple shock configurations to suit different driving styles and performance needs. Available options include nitrogen-charged N3 shocks for balanced daily driving and light off-road performance, V2 monotube shocks for improved responsiveness and heat dissipation, or premium M1 monotube shocks for enhanced damping control and off-road capability. Designed as a straightforward bolt-on system with no cutting or drilling required, this kit delivers the stance, strength, and ride quality expected from a premium Super Duty suspension upgrade.
